QThread::wait: Thread tried to wait on itself QThread: Destroyed while thread is still running 为了让子线程能够响应信号并在子线程执行槽函数,我们在InheritQThread类构造函数中添加了 moveToThread(this) ,此方法是官方极其不推荐使用的方法。那么现在我们就遇到了由于这个方法引发的问题,我们把moveToThread...

在run函数中添加QThread::exec()来启动事件循环。(注意:在没退出事件循环时,QThread::exec()后面的语句都无法被执行,退出后程序会继续执行其后面的语句); 为QThread子类定义信号和槽; 在QThread子类构造函数中调用 moveToThread(this)(注意:可以实现构造函数在子线程内执行,但此方法不推荐,更好的方法会在后期的...
Maybe there is a better way to do this though. Also enabling me to show this countdown thing I thought of. EDIT: ok I tried things and it might be stupid but it seems to work this way. I thought that I might as well keep the thread and the worker alive until...
I first noticed this when I got back to doing the 8.4.0 prerelease builds 2024-04-06 after a month or two away. I tried upgrading the qt-octapp_5 formula from 5.15.12 to 5.15.13 (which core qt@5 is on), and it failed with this error. But then I reverted to 5.15.12, and th...
The QHotkey class itself is reentrant - which means you can create as many instances as required on any thread. This allows you to use the QHotkey on all threads.Butyou should never use the QHotkey instance on a thread that is different from the one the instance belongs to! Internally...
the connection of the sky to the land, and offers creative composition options. However, the 2024 eclipse occurs close to midday (1:40 pm) when the sun is high, and the landscape of Central Texas is not exactly superlative. Therefore, this time I tried my hand at capturing a close-up ...
In this tutorial, I could not get the file size before the download, I mean, not every site I tried. The progressDialog is failing to display the progress in such a case. Here are my tries: Using slot : void HttpDownload::updateDownloadProgress(qint64 bytesRead, qint64 totalBytes) ...
